During strong quakes, the propagation of seismic waves in soil layers involves nonlinearities changing with the excitation level. A nonlinear hysteretic law is necessary to describe the variations of the stiffness and the energy dissipation during the seismic shaking. Furthermore, the influence of the pore pressure (cyclic mobility and...

The influence of lateral heterogeneities in alluvial deposits represents a topic of particular interest in the field of urban planning and engineering design of structure and infrastructures. This work is focused on the effects of such heterogeneities on the shear strains produced within the recent alluvial deposits of the Tiber River in Rome...
